lets seeeee. half shaft difference between the spline counts for "strength" is well........ technically an interesting dialogue - for sure.

I've done some serious towing with the D/R tranny in its original NA 86 wagon, and its seen near equal - dare i say its also seen harder driving as well in the turbo wagon i swapped it to.

Spline counts means "Stronger shafts"? Might be, but I have yet to see any realworld different in strengeht... now boot life is relative to the road/offroad hazzards and so you may be doing a warranty replacement of a halfshaft (like have done twice plus) sooooo.... its up to you.

BTW from my humble, yet simple bio and geocities site ...and even the galley of images i have on here.... you can see my GL-10 turbo wagon and her D/R setup..... BTW I have now had to substitute the XT6 FT4WD tranny for the D/R as grinding started to occur......

I have two D/R's and both have different internal problems... so I'm figuring on a rebuild from the two of all the best parts and wammo... ressurected D/R for the "Silver D/Ragon"

Thanks for the thoughts. I'm planning on just using the axles that came with the dual range. It seems nobody has had a problem so it does not seem worth the effort. I'm about halfway through it now. I just sat the tranny on the ground. Might have it done in a few days around work and stuff.
